Shearing control method of high-speed flying shear

The embodiment of the invention provides a shearing control method of a high-speed flying shear, and relates to the technical field of electrical automation control. The shearing control method of the high-speed flying shear comprises the steps that under the condition that the blade position is located at the crossed position, the steel pipe shifting position deviation P is calculated; under the condition that the position deviation P exceeds an error allowable range, calculating a compensation value T of a shearing starting parameter T; and updating the compensation value T to the shearing starting parameter T. The high-speed flying shear shearing control method can detect the shearing state of the high-speed flying shear, improve the control precision of the high-speed flying shear, improve the operation stability of the high-speed flying shear and reduce faults. 本发明的实施例提供了一种高速飞剪剪切控制方法，涉及电气自动化控制技术领域。高速飞剪剪切控制方法包括：在刀刃位置处于交叉位的情况下，计算拨钢管的位置偏差△P；在位置偏差△P超出误差允许范围的情况下，计算剪切开始参数T的补偿值△T；将补偿值△T更新到剪切开始参数T上。高速飞剪剪切控制方法能够能
